Understanding the electrochemical and complexation behavior of actinides in solution is very fundamental for the assessment of environmental impact on the geological disposal of radioactive wastes, such as predicting the migration behavior of these nuclides in the geosphere. Especially, uranium(U) and neptunium(Np) are some of the important nuclides for this kind of research.Therefore, in order to investigate the electrochemical and complexation properties of U and Np, cyclic voltammetry (CV), electrolysis, and X-ray absorption measurements were carried out in various types of aqueous- and nonaqueous solutions. In this presentation, some remarkable results are introduced and discussed to draw a general conclusion about the electro- and complexation chemistry of U and Np in solution.
